In terms of overall gaming performance, the AMD APU A6-5350M Dual-Core is noticeably better than the Intel Celeron 877 1.4 GHz when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

The APU A6-5350M Dual-Core was released less than a year after the Celeron 877 1.4, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The APU A6-5350M Dual-Core and the Celeron 877 1.4 both have 2 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, the APU A6-5350M Dual-Core and the Celeron 877 1.4 may still be able to run slightly older games fairly effectively.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The APU A6-5350M Dual-Core and Celeron 877 1.4 are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the APU A6-5350M Dual-Core has a 1.5 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is probably a good indicator that the is superior.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The APU A6-5350M Dual-Core has a 512 KB bigger L2 cache than the Celeron 877 1.4, and although the APU A6-5350M Dual-Core does not appear to have an L3 cache, its larger L2 cache means that it wins out in this area.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.

The Celeron 877 1.4 has a 18 Watt lower Maximum TDP than the APU A6-5350M Dual-Core (though they were created with the same size 32 nm manufacturing technology). What this means is the Celeron 877 1.4 will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewAPU A6-5350M Dual-Core is a middle-class mobile processor based on the 32nm, Richland micro-architecture.
It offers 2 Cores, initially clocked at 2.9GHz that go up to 3.5GHz, in Turbo Mode and 1MB of L2 Cache. It features integrated Graphics called Radeon HD 8450G which offer 192 Shader Processing Units and are substantially faster than previous Radeon HD 7520G. The max memory speed supported by the CPU is DDR3-1600. It consumes up to 35 Watt.
This CPU should only be paired with fast-middle-class GPUs such as Radeon HD 7770M/GeForce GT 650M.
Intel Celeron 877 1.4GHz is a cheap dual-core CPU for small laptops based on the Sandy Bridge architecture but with most of its features disabled.
It features Integrated Graphics clocked at 350MHz that go up to 1000MHz in Turbo mode and the memory controller supports DDR3-1066 and DDR3-1333.
Despite its puny structure, the performance isn't as horrible as it may sound and its power consumption is extremely low.
